B)larger outer ears
C)a thinner and therefore more sensitive tympanum (eardrum)

The tectorial membrane and hair cells in the ear are responsible for transducing sound waves into nerve impulses that can be interpreted by the brain. A wider range to the tectorial membrane and hair cells would allow a dog to detect higher frequencies of sound, which are typically outside the range of human hearing.
